Question

Quizplus · Accepted Answer

Mark's behavior of flailing and talking during sleep indicates that he is acting out his dreams. This is characteristic of REM sleep behavior disorder, where the muscle paralysis that normally accompanies REM sleep is absent, allowing the person to act out their dreams. Sleep apnea involves interruptions in breathing during sleep, somnambulism (sleepwalking) involves walking or performing other activities during sleep, and night terrors involve sudden arousal from sleep with intense fear and panic.
